- ar - A utility for creating, modifying and extracting from archives.
- c++filt - Filter to demangle encoded C++ symbols.
- dlltool - Creates files for building and using DLLs.

- gprof - Displays profiling information.
- nlmconv - Converts object code into an NLM.
- nm - Lists symbols from object files.
- objcopy - Copies and translates object files.

- ranlib - Generates an index to the contents of an archive.
- readelf - Displays information from any ELF format object file.
- size - Lists the section sizes of an object or archive file.

上面比较重要的有ar, nm, objcopy, objdump, readelf, strip.
ar可以生成static library;
nm可以list symbol of object files;
objcopy可以转换image格式，例如将elf格式转成bin，或者hex;
objdump可以打印出object files中的可重定位的symbol;
readelf可以从elf中打印出symbol和section的很多信息;
strip可以删除ELF file中的symbol或者section信息。
